rFIOE rnnsarroie iraniennes To all whom uf may concern.

Be it known that l, PAUL lnsrnna, a citizen of the Republic of France, and a resident of Lille, Department of N ord, France, have invented certain limprovements in and Relating to `Pulsation Apparatus, of which the followingis a specification.

My invention has reference to improve-4 ments in and relating to pulsation apparatus, 'and it consists in improved means for bringing aboutI the reversal of the action in pulsation apparatus of any kind in which a tluid or liquid is alternately admitted to and discharged from a closed chamber. The means in question are intended to act upon a 3-way cock or some equivalent device which is adapted, as is necessary in apparatus or' this kind, to place the apparatus during the first part of the pulsation in communication with the inlet of any fluid or liquid, such as steam, air, gas, or water, cc., and during the second part of the pulsation in communication with the'exhaust or outlet.

I have illustrated my invention in the accompanying drawing, in which:

Figure 1 shows an apparatus for raising a liquid by means of compressed air; Figs. 2 and 3, show details of the same on an enlarged scale, and Fig. shows a variation of the apparatus arranged to act as an aircompressor.

In the drawings, l represents a cylinder provided at its base with a back pressure or check valve 2, through which liquid or luid enters, and a valve 3 of similar character through which the said liquid or fluid is forced out. A pipe 4, which communicates with an opening in the cover 5 of the cylinder, places the upper end der in communication, byv means of a 3-way cock 6, either withan inlet 7 for fluid under pressure, or with an exhaust S through which said fluid escapes into the atmosphere. rll'he motive medium employed to operate Said valve 3 is a float-not a hollow float capable of floating of itself, but a structure which is open 'to receive a liquid body,vor a solid member may be used; either structure being balanced by means disposed exterior-ly of the cylinder. This member, which indicated at il, is suspended from a wire 10 extending through a stulling box l1 in the cover 5 of the cvlinder. and passing around a pulley 12; a counter-weight 13 being hung' from the same on thc other side of the pulley. The pulley lf2, which' is in the form of Specification or Lettera' Patent. Application led September 29, MGE.

tmer or weight 16 which j on the Patented, Nov.. 5, 1912. serial no. 455,273. l

antiek, carries two pins, 14- and 15, mounted diametrically opposite each other, which pms are adapted to alternately raise a han1- is loosely mounted pulley spindle. Fig. 2 shows the pulley 12 withxthe pins 14 and 15 and the hammer 16, on an enlarged scale. When the mlember 9 rises, due to admission of liquid to the cylinder` 1, the pulley rotates from left to right. The pin 1 4 raises the hammer, and the moment the hammer passes the center of gravity it falls on the other side, thereby shifting the valve. When the member 9 descends, the opposite eiect is prod uced. The hammer falls alternately to the right and to the left and this changes the position of the mechanism and reverses the movement through the intermediary or' a suitable device. The simplest device for this purpose is that shown in the drawings, z'. e., the 3-way cock indicated at 6, the axis of which is in alinement with the axis'of the pulley. i

The action ol the apparatus is in this case as follows: Assuming the apparatus, as illustrated, to be full of liquid and the cock 6 to be open for the admission of compressed air, the air passes into the apparatus through the inlet 7 and pipe aand forces out the liquid. At the same time the member 9 descends and causes the pulley to rotate and raise the hammer by means of the pin l5.

instance to the left, Fig. 1, (or in the reverse view, Fig. 3, to the right) and, in falling, engages a projection 17 on theJ stem of the cock 6 and movesthe latter with it, imparting a quarter of a revolution thereto.- This places the apparatus in communication with the exhaust 8, and thereupon the cylinder is recharged with liquid entering by the valve 2, the member 9 rising and bringing about movements the reverse of those just described. Fig. 3, shows the projection 17 carried by the stem of the cock whereby itmay be operated by the hammer or weight 1G. A guard or stop 16Ct serves lto arrest the hammer when it falls to either side so as to maintain the cock 6 in the proper positions. A similar movement exists in the Kennedy water-counter but all the mechanism is inter-nal. In the present case owing to the em ploymcnt of the connecting wire which passes freely through the cover, I have been able to devise an external movement.

lWhen the hammer reaches its highest point it falls over on the other side, in-thiseol Loewe? I ln the apparatus shown in Fig. l, the member, 9 acts, through`r` the intermediary of e pulley 20, on a pulley 12@L having the vpins 14 end 15, which latter pulley is mounted on a spindle in alinement with the axis of the 3-Way cock 6, the seid cock being l adapted to place the cylinder in communicetion at one time with the inlet 7" for Water under pressure, and at another time wi th the exhaust 8?. The cylinder lb is provided at its upper end with two back pressure valves 21 and 22; air being drawn in through valve 21 es the Water is flowing out, While the air which is compressed 'in the cylinder as it is being again filled with Water is forced `out through the Valve 22.

I claim:

The combination of a chambered cylinder adapted to receive liquid, a movable weighted member vWithin said cylinder, provision for the inlet end outlet of liquid to and from 'l said cylinder, provision for th inlet and A and outlet of one of said outlet of uid under pressure to act on seid liquid, a rotatable .valve controlling the inlet bodies, a stem on said valve, a. ulley mounted on the same axis as seid va, ve, e freely movable countertion between the eounterweight and the Weighted member Within the cylinder, the hub of said weighted arm engaging the projection on the valve stem and shifting" smid vulve when turned so as to change the direetion of ilow through the sume of one of 5"" the bodies within said cylinder.

In testimony whereof, I have signed my nume to this specification, in the presence of two subscribing` Witnesses.
